You cannot repair virtual disks after you reconnect the corresponding physical disks in a JBOD array in Windows Server 2012

Symptoms


Consider the following scenario:
  • You install a Just a Bunch of Disks (JBOD) array on a computer that is running Windows Server 2012.
  • You create a storage pool for all physical disks. Then, you use the physical disks to create virtual disks. 
  • You disconnect certain physical disks.
  • The virtual disks that correspond to the disconnected physical disks are in the Degraded state. 
  • You wait for 10 minutes.
  • You reconnect the disconnected physical disks, and the physical disks are recognized as healthy. However, the physical disks are in the Retired state.
  • You manually set the usage type of the physical disks to AutoSelect so that the physical disks are not in the Retired state.
  • You try to repair the virtual disks that correspond to the reconnected physical disks by using the Repair-VirtualDisk cmdlet.
In this scenario, the Repair-VirtualDisk cmdlet exits immediately, and no error message is returned. Therefore, the physical disks return to the Retired state, and the virtual disks remain in the Degraded state.

Cause


This issue occurs because the columns for the physical disks that you disconnect are marked as FAILED. Therefore, Windows assigns the Retired status to the physical disks.
